How to model braided nylon sleeve
Add a mesh circle to your scene
Extrude it vertically
Poke its faces with Alt + P
Remove the vertical edges by selecting one of them and pressing Shift + G > Select Grouped > by Direction
Remove the triangle faces with the same operator by Polygon Sides





Add an empty object to the scene
Add a Bezier Curve object too
Now add an Array modifier to the circle
Clear the pre-defined relative offset options
Check the Object Offset option
Pick the previously added empty object
Set it to Fit Curve mode
Pick the previously added Bezier Curve
Now adjust the Position of the Empty to match the rotation and the height
Move it up half the distance extruded in point 2





Rotate it about the Z axis $360°$ divided by twice the number of edges of the circle (by default a circle has 32 edges so $360° / (32 * 2) = 5.625°$)
Rotate the whole Circle + Empty in the Y axis $90$ degrees
Add a Curve modifier and pick the same curve used in the array
Now add a Wireframe modifier
Adjust the curve's shape as necessary





Control the dilation/contraction of the nylon sleeve with the curve vertex radius





Enter edit mode in the curve, select a vertex and press Alt + S by default.





Profit!
